Vaisala WMT700 - Manual (Page 57)

Chapter 3 _______________________________________________________ Functional Description
Missing Readings and Error
Indication
If WMT700 is not able to measure the wind, it indicates a missing
reading in the output. Most common reasons for measurement
problems are foreign objects (such as ice, birds, or other foreign
objects) on the line of measurement or sound reflections from
nearby objects (such as wind tunnel walls).
The default error indication is an out-of-range signal, which is
more than 10 V or 20 mA, but other error settings can also be
configured.
Example
To set analog output 1 error indication in current mode to 2 mA,
set the analog output error value to 0.002. Enter the following
command:
S aout1err,0.002
For more information, see section Appendix D, Configuration
Parameters, on page 205.
